The invention discloses a brake arm length compensation device, and relates to the technical field of train braking technologies, in particular to a brake arm length compensation device of a heavy haul train. The brake force arm length compensation device further comprises a brake force compensation control device, a brake force balanced distribution control device and an execution mechanism. The actuating mechanism is arranged in the middle of the movable free-center lever and is coaxially hinged with the middle pull lever; the braking force compensation control device is arranged on the brake cylinder and is communicated with the brake cylinder; the braking force compensation control device is further connected with the executing mechanism through a communication air path. And the braking force balanced distribution control device is arranged on the vehicle main body structure, the vehicle chassis and the force transmission cylinder rod, and is connected with the execution mechanism. According to the technical scheme, the problems of train braking air pressure leakage, insufficient train braking force, non-uniform train braking force distribution and the like which are easily caused in the running process of the heavy-load train in the prior art are solved.
